Always thoroughly clean all parts before returning parts and pumps.
Please also pack the returned goods in a suitable bag to prevent residual
moisture from leaking into the surrounding packaging.
Together with the returned pump, please include a copy of the product data

can use the required PPE when working with the pump.

Before returning devices and system components, they must be

Product-carrying lines and components must be flushed with sufficient
water to prevent the risk of injury to our personnel from chemical products.
